Ariel Von Solistia, the second prince of the Solistia Empire, widely known for being a fool, encounters a crimson-haired girl who immediately captivates him during their very first meeting.

Both, knowing nothing of love, begin encountering each other everywhere, sometimes by chance, sometimes by coincidence, and with each meeting, their feelings deepen.

However, the girl hides a secret behind the mask she wears… she is known throughout the empire as a villaness.
